UNITED STATES PATENT @Erica ALEXANDER FLEMING, 0F CEDAR TOWN, GEORGIA.

'COTTON-CHOPPER.

SPECIFICATION forming part o1 Letters Patent No. 380,429, dated April 3, 1888.

Application tiled December 8, 1886. Renewed February 6, 1888. Serial No. 268,166. (No model.)

To will whom it may concern:

Be it known that 1, ALEXANDER FLEMING, a citizen of the United States of America, re` siding at Cedar Town, in the county of Polk and State of Georgia, have invented certain new and useful Improvements in Cotton-Choppers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in cotton-choppers; and it consists in the construction and arrangement of the parts whereby the stands are formed from either side.

In the drawings, Figure lis a side elevation of a machine provided with this invention. Fig. 2 is aplan View of the same. Fig. 3 is a perspective View of the choppers detached.

The frame-work and running-gear shown in the drawings is the same commonly used in this class of machines, and it is not claimed, broadly, in this present application.

This present invention relates particularly to the chopper mechanism, so Ithat the parts above referred to will only he mentioned in so far as they are connected with the action of the chopper proper.

The letter A designates a shaft journaled in the frame-work of the machine and the end of a depending bracket, B,which is attached to the handle of the machine. At the inner extremity of the said shaft is a beveled cogwheel, C, which engages a similar wheel, D, upon the axle of the machine. The said axle is rigidly attached to the wheels upon which the machine rests. Between its bearings the said shaft Ais provided with an enlargement, E, which forms a shoulder against the frame, and,in conjunction with the cog-wheel C,steadies the said shaft A. Set in the said enlargement E are the chopperblades F. These blades are constructed in pairs, substantially as shown, separated at the outer extremities the width desired for a stand of seed. The faces of the blades of each pair are turned to- 4 5 Ward each other at their outer ends, so that the dirt is thrown from each to the center as they pass through the furrow-ridge. These blades are so set around the enlargement E that in the progress of the machine the rear edge of the second pair falls upon the furrowridge at the point where the outward edges of the preceding blades cut through, and so on, each pair following upon the ridge the width of the blades in advance.

In the operation of this invention the rotary motion is imparted to the shaft A, by means of the wheels of the machine, through the beveled cog-wheels D and C. The speed of the rotation of the said shaft is regulated by means of 6o this gearing by substituting a larger or smaller cog, C, as slower or faster rotation is desired. The cog D is adapted to move back and forth upon the axle ot' the machine to accommodate such substitution.

Vhat I claim is- 1. In a cotton-chopper, a shaft adapted to be rotated by the movement of the machine and provided with chopping blades extending from the periphery, said blades arranged in pairs to act simultaneously, the adjoining edges of said blades being separated the length of a stand and their cutting-faces turned obliquely toward each other, substantially as and for the purpose set forth.

2. In a cotton-cliopper, blades for forming stands, operating in pairs, the blades of the said pairs being separated the length of a stand and their cutting-races turned obliquely toward each other, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ALEXANDER FLEMING.
